黄河碛口水库运用方式研究

黄河中游干流水为不仅需要调节径流，尤其重要的是必须调节和处理好泥沙，才可能长期保持一的有效库容，取得长远的设计效益，所以，水库运用方式比少沙河流上的水库复杂得多。本文根据黄河综合治理方针及碛口水库的开发任务，分析了水库的水沙特点，库容分布，库区地形特征及水库对上下游的影响等因素，研究论证了碛口水库水库实行泥沙多年调节，初期汛期采取高水位蓄水的运用方式是适宜的。

Study of Qikou Reservior Operation Program

o obtain long term design effects and keep certain effective storage,reserviors in middleYellow River is not only needed to regulate water flow but also with more importance to adjustand deal with sediment. Therefore,the operation programme of reserviors are much more complicated than those in rivers with less sediment contains. The paper analysed the characters of waterflow and sediment of Qikou reservior,its storage distribution and surrounding land form and theirinfluences on upper and lower reaches of the reservior,as well studied and demonstrated that theapplication of sediment regulation of years,high level retaining water at very beginning flood season are proper operation in Qikou reservior.
